Two-lined message list: Opera Mail will now default to "list on the left, message on the right", with the newest message on top, and showing message threads.

Mail grouping: Opera will automatically group messages by date. You can also group them by unread status, by pinned status, or not at all.

Cleaned up look: The mail toolbars are simplified, and icons have been redesigned.

New settings dialogs: The "View" dropdown menu with all its sub-menus has been replaced by an overlay dialog that can be reached by clicking the "wrench" button.

Pinning: You can now "pin" messages with one click in the message list or in the message headers, to mark a message for attention. This pinning is mapped to the IMAP \Flagged feature, so it corresponds to "starring" and "flagging" in other IMAP clients, and with Gmail's starred messages.

The star menu in the address field allows you to quickly bookmark a page or to create a Speed Dial entry.

HTML5 Parser

Implemented the HTML5 parsing algorithm

The HTML5 specification defines a set of parsing rules for all markup, whether valid or invalid. Once all browsers have HTML5 parsers, the same markup will produce the same DOM across all conforming browsers. Hence, the HTML5 parser will improve website compatibility.
